Mojo Audio Mystique EVO

Ideally, a system should have only one ground point to the mains through one mains lead. Because you can get small earth loops happening if everything has a mains earth plug
All equipment are grounded to each other via the interconnects from source to poweramp if the power amp has the earth to the mains.
  
The only time a second mains earth is needed is if cd transport using the optical (toslink) connection to the dac. Then the transport need to have a mains earth as well.

I’m playing louder than normal (about +10db) as well and the sound only becomes fuller - never strained nor distorted. And while playing at higher than my normal volume, I can hear more of the delicate details and dynamics of this excellent DAC.

That’s what a "good" R2R Dac does, discrete or chip. On a system that handle’s it.
It gives incredible punch and definition (boogie factor) to the bass yet a rich/fullness to the mids and above, all you want to do is turn it up.
Then suddenly your amp runs out of steam on a dynamic swing, you realize, your wife, and your neighbors say "wow" I went too far this time, That Was Loud!!.

This sounds like it's going to give the MSB's, Halo's, Denafrip's, a real run for the money, hope a mag that also does tests and measurements like Stereophile does a review on this.
